TO ALL 'WI-IOM IT MAY CONOERN:

Be itlcnown tliat I, WILLIAM B. LODGE, of l):uibury, in the eount-y'of Fariield, and Stat-e of Connecticut, have invented a certainl new and useful Improvement on Pulling-Stocks, of which the following is a full, clear, and exact description. reference being had to the accompanying drawing, forming` part of this specification, and in which- Figure 1re-presents a side elevation oi' a falling-mill, constructed according to my improvement.

Fig-ure, a longitudinal section thereof; and

Figure 3 a plan ofthe same.

Like letters indicate,corresponding parts throughout the several figures. l

The nature of my invention consists, firstly, in a novel mode of raising the hammers or beaters bya smooth cam or friction motion in the place of -the ordinary toe and wiper action, and whereby friction is reduced; also in regulating the fall of lthe beaters, by means ot' a spring or springs made adjustable as regards their tension to control the force of the blow; likewise said invention farther consists in a. hollow box-like formation on the outside or surrounding the bed and bosom of the mill, and supplied with water heated by steam or otherwise; also in an open-work or perforated bosom, for the circulation of `the heated wat-er through the same, and in constructing the bosom of aseries of rollers that assists in turning the goods, and admit lof a more rapid motion being given to the stocks said invention also embracing India-rubber or other like soft and elastic toes to the heaters, to prevent injury to the goods' being fulled or felted. Y

Referring to the accompanying drawings, A represents the standards and framework of the mill; B, the swinging beaterswor hammers, hung or pivoted as at a, for operation as in other falling-stocks, but differing therefrom in the following respects: Instead of lifting the beaters by the ordinary toe and wiper action, which induces much wear and friction, I cause said beaters or hammers to be raised by means of revolving cams, or smooth f'rictioinbloeksGj'cutaway substantially as represented in iig. 2 so as to lift during a portion of' their revolution, and suddenly let drop the hammers after 'boingraised, said cams thus operating ina smooth and easy manner, on, say, the Vbachs of slices I, fa'st to the hammers, and being, it may be, rotated by gear 6 c, on horizontal shafts D E, the latter of which carries the cams.V A further difference also is to be foundl in means for controlling the force of the blow, consisting of a spring or springs, F, arranged within and acting on drums,

'Z, that carry straps c, fast at their one .end to vsaiddrums, aiid at their others to the hammers, the fall of which, or force of blow, they serve to regulate to suit different kinds or qualities of work, accordingly as more or less ltension is given to the springs,`by, say, an endless scrcw,f, working-into a worm-wheel, g, fast on the shaft that carriesthe drums; such means, however, may be materially varied to produce the same action or effect in substantially like manner. Likewise, ins/tend oi the toes G of the hammer being made as usual of wood or other like hard material, I preferably construct them of India rubber, gatta percha, or other analogous pliable and elastic substance, which prevents cutting of or injury to the goods undergoing the process of felting or falling.

His the bed of the stocks, `which, with the Ibosom I, is arranged within a hot-water box, J, supplied in any suitable manner, and'heatcfl by steam or otherwise, the same materially assisting and improving the falling of tbe goods. To yet further improve, however, the cleansing and falling or felting ofthe work, I make the bosom I of a perforated or open-work characterto allow of the circula-tion of hot water from the box J amongst the goods, and which'perforated or other open-work construction of the bosom is or may be preferably givcn'it by forming said bosom of a series of' rollers, s, that not only allow of the passage of the water in between or through them, but enable the goods, in being beaten by the hammers, to turn more freely, andso render more uniform and thorough the falling of, a numberof goods worked in mass, besides rendering a more rapid action Aof' the beaters feasible. I

Fulling-stocks thus constructed maybe so tted as to be both portable and durable, and will accomplish more work in a given time than the ordinary stocks.

What I cla-im as my invention, and desire to secure by Letters Patent, is-

1.- The combination, with the hammers `or beaters B, of the cam or friction-blocks C, operating to @fleet the lift oi' the former, and to suddenly release,themr whcn raised, substantially as specied.

2. The combination, with the hammer or hammers of the mill, of an adjustable spring tension device, arranged to control their fall, essentially as herein set forth.

3. The combination of the toes G, made of India rubber or other analogous soft'material, with `the hammers B, substantially as specified. l l

4. The combination with the beat-er B of the hot-water box or bath J, and the bed and bosom H I, oper ating on theniaterial being fulled substantially as specified.
